Flat gate valve flow resistance is small, non-reduced flow resistance and short pipe flow resistance is similar. The flat gate valve with diversion hole is installed on the pipeline and can be cleaned directly with the pig.
The gate plate slides on the surface of the two valve seats. The plate gate valve can be applied to the medium with suspended particles, and the sealing surface of the plate gate valve is actually positioned automatically. The seat sealing surface is not damaged by the thermal deformation of the valve body. And even if the valve is closed in the cold state, the hot elongation of the stem will not overload the sealing surface. At the same time, when the valve is closed, the plate gate valve without a diversion hole does not require a high accuracy of the closed position of the gate. Therefore, the electric plate valve can control the opening and closing position with a stroke.

Synthetic resin roof sheet if made of high weather resistant ASA engineering resin as the surface material, and high-quality PVC wear-resistant resin as the bottom material, which is formed by one-time co extrusion technology. ASA high weather resistant engineering resin layer on the surface is the most critical, which directly affects the service life of synthetic resin tile.
Its service life is generally about 30 years. Synthetic resin roof tile does not need repair and maintenance in the use process, saving time and energy, and convenient installation.
